Hi everybody,
I am trying to repair a circuit board. However, I can't find what are the 2 of the components by looking at their markings. 577X LEVB looks like regulator to me, and A40A 585V looks like opamp. If you have any idea what exactly are they, can you tell me? I am going to add more information about A40A's surroundings.




Thanks in advance.

Hello strahd_von_zarovich,
I think you are correct in that the component marked: A40A 585V is an Op-Amp. And going
by what I was able to search, there's a good chance its an OPA40A Single-Supply, Rail-to-Rail Operational Amp.
As for the 577X LEVB, once again I'm sure you're correct in that it might be a voltage regulator, a 5 volt type as
you've ascertained by your markings. I was unable to find any info on it though. :-(
By the way, could you please tell me what program you used to mark the PCB? It almost looks like Micro$oft Picture It 7.
Regards,
Relayer
 

Hi, I finally figured out which components are they. One of them is OPA2340 and other one is LP3982. :-D
If you are talking about red lines, I drew them on Paint :-D
Regards.
